Cheap Is More Than a Price: Inside One Osaka Vending Machine Business

Customers see the price. What they do not see is the product selection, inventory control, physical labor, and constant adjustment behind it.

Oinahare operates ultra-cheap vending machines in Osaka. Atsumu Matsumoto, 26 at the time of filming, is the second generation of the family business. His work shows that affordability is not a single trick—it is an operating system built through daily decisions.

Affordability Is Built, Not Found

Oinahare became known partly for selling 10-yen drinks during its early years. That price is a historical example, not the current price of every product.

Its exact purchasing routes remain confidential, but low-cost sourcing is only one part of the equation. Unsold products become excess stock, while longer routes and frequent restocking add cost. Coffee tends to sell well in central Osaka; water and tea move more quickly in suburban and industrial areas. Every location requires a different judgment about what to buy and where to place it.

Invisible Work and Practical Change

A vending machine looks automated, but its operation is not. Products must be selected at the warehouse, loaded, delivered, counted, and restocked. Sales, cash, and change also need to be checked. On a busy day, Atsumu may handle around 300 cases by himself.

Even the product cards reflect changing costs. Manufacturers once supplied thick plastic displays. As prices rose, Oinahare began printing product images on paper and laminating them in-house. It is manual work, but it lets the company make only what it needs.

Atsumu also wants to digitize tasks such as sales records where technology can reduce unnecessary effort. The goal is not to replace everything analog. It is to preserve useful knowledge while changing work that has become a burden.

Turning Experience Into a System

The business began when Atsumu’s father planned a laundromat and installed a vending machine as an alternative to a dedicated change machine. From there, he expanded through instinct and close observation of demand.

Experience held in one person’s memory is difficult to pass on. Atsumu therefore assigned an ID number to each machine, making locations and equipment easier to track. Succession, in this case, means translating intuition into a system other people can use.

At its peak, the business operated more than 600 machines. At the time of filming, it managed around 370. Consolidating the network is not simply decline; it is also a decision to keep the operation manageable.

Atsumu wants Oinahare’s machines to remain inexpensive, varied, and accessible even to children. But affordability cannot survive if the work behind it is unsustainable. Keeping prices low and redesigning the operation are part of the same challenge.

Look again at one familiar vending machine and it becomes something else: a small business shaped by labor, local knowledge, and family history. Behind its price is a quieter side of everyday Osaka.
